THOMAS HENRY GARLAND, OF CIIICAGO, ILLINOIS.

CAB-VENTILATOR.

To all whom it may concern:

Be it knownthat I, THOMAS HENRY GAR- LAND, a citizen ofv thev United States, and a resident of Chicago, in the county of Cook aand State of Illinois, have invented a new and Improved Car-Ventilator, of which -the following is a full, clear, and exact descrip-A auxiliary or supplementary passage in'which tion.

The invention relates to car ventilators such as shdwn vand described in the Letters Patent of the United States, No.v 800,438, granted to me on September 26, 1905.

- The object of the presentinv'ention is to provide a new and improved car ventilator,v so arranged as to insure eater efficiency in ventilation of the car an to provide for .the ventilation of berths or compartments in the 'car that may be separated fromthe 'clearV story of the car, without danger of smoke, cinders, rain, snow, etc., passing' into the car by way .of the ventilator.

The invention consists of novel features and parts and combinations of the saine, as will be more 'fully described hereinafter and then pointed out in the claims.

A `practical embodiment of the invention is represented in the accompanying drawings forming a art of this specification, in which similar characters of reference indicate corresponding parts in all the views.'

Figure 1 is a perspective view of the improvement as applied; Fig. -2 is an enlarged sectional plan view of the Vsaine on the lin 2-2 'of Fig. 3; Fig. 3 is a sectional side elevation of the same on the line 3-3 of Fig. 2; Fig. 4 is a transverse section of the improvement as arranged for lVentilating the clear lstory of the car and berths separately; Fig. 5 is a sectional plan view of the same on the side elevation of the same on the line 6-6 of the inner end of the conductor A and tervI ninatin ,at their outer ends at or near the side of t e ca r, as plainly lndicated in Fig. 2,

tracted discharge ends E2, E3 of'cowls E, E', having their flaring entrance ends E4, E5 pointin in opposite directions, that is, between te front and rear of the car.

By the arrangement described, the passages A and A3 are dominated by the cowls E and E while the center passage Az is an asucticn is .pro uced by lthe'discharge of the air from the cowl passages A', A2, as hereinafter mo'refully described. The center ass sage` A2 rovides a clear opening or uct from the inner end of the conductor A to the outer terminal thereof, so that a large amount of impure air in the'car can be drawn out and discharged by way of the said center passage A2 to the outside of the car.

The VactiCHLotheventilator when the car is in motion is asl follows: When the car travelsv in the direction of the arrow a', the 'current of air caused by the forward movement of the car enters the flaring end of the cowl E at E4 and passes through the outlet E2 into the passage A of the condnctorA. The action of this current passing through the cowl E and the passage A produces a partial vacuum at the inner end of' the conductor A, whichcauses the foul air in the car` to enter the conductor A-and be drawn out. through the assage A. When the current of air from t e cowl E and the air from the conductor A through the charged at the outer end o the passage A of the conductor A,- it comes in contact with the current of air that is passing along the side ofthe car, caused by the orward'motion of the car, and by this outside current of air the air from the passage A is made to bend passage A is dis?4 around over and passes the outer end of the.

auxiliarypassage A2. By this action a partial vacuum is produced at the outer end of the auxiliary passage A2. vThis artial vacusame action oi the air from the' assages-A' and Abending over the outer enr. .of the pas- When the car travels in the oppo-fv site direction the action is' the same; that is,

sage A3,

the air entering the cowl E vat E produces a suction at the inner end of the passage A3 and :at the outer ends of the passages A2 and A. y

The ventilation of the car is regulated by 6 fpening. and closing the usual deck'wi'ndow in front of the window-board (1,"'Which'V opens and closes the opening into'thejcon ductor A.

'In the arrangement illustrated in Figs. 4,

1.0"5 and 6, two suction' devices are employed,

-one superirposed upon the other, that is,` a

conductor is arranged on the top of the conductor'H held on theroof B of the car, and the inner Vend of the upper conductor G is connected with the'WindoW-'board G, Whjle A' the inner end of the lowerfconductor H is connected with the dischar e end I of aduct -I, and which discharge end extends through 4the roof B of the car, and the duct I.- extends 'down the side of the car to aberth or other Iparticular.part in the lower' portion of the car to be ventilated. The inlet end I2 of the duc't Iis perforated, as illustrated in 'Fig 4, and a damper J is arranged in the duct above the perforations, to allowof o ening or closing the duct Whenever it is The conductors and H are provided With trainiversely44 extending Vpartitions G, H', terminating at `their inner yen'ds a distance from the'inner'ends of the conductors G and H, -so as to, for1n separatejpassa'es,into which c en the-contracted 4inner ends K2, 4K" and L?, L, respectively, the said cowls havingtheir entrance ends K1', K5 and L4, L5 arranged in theo posits-directions, the saine as above descriied relative tothecoWls-E, E. p The `action of each suction device described is the sameas above referred to relative'to the arran ementshown and described in Figs; I, 2 an 3, that is, foulv air'can be inner ends.
